Muscle Repair During Implant Removal and Revision

Let's talk about muscle repair with implant removals and revisions, because this is one of the most under-discussed parts of explant and plane-change surgery, and it makes an enormous difference to your result.

When we place a breast implant under the muscle, the muscle we're talking about is the pectoralis major.

To get an implant underneath it, we separate the muscle from your chest wall along its lower and inner attachments. That whole muscle can then be elevated, and the implant slides underneath. (For the full map of placement options, see subglandular, submuscular, dual plane, and subfascial.)

Here's the consequence: that process stretches the muscle out and leaves it in a position that isn't natural for a lot of people.

This surprises patients, and it's important to understand before you explant.

That stretched-out muscle is no longer properly connected to the chest wall. So when you remove the implant, the muscle tends to do weird things.

The logic is simple: the implant was keeping everything tight, so it looked relatively normal. Once the implant is gone and the space has been stretched, that unanchored muscle can look quite strange.

This is exactly why, if I'm removing an implant altogether that sits under the muscle, or moving an implant from under to over the muscle, I always make a point of repairing the muscle back where it belongs.

There's a technical wrinkle. Because there's been an implant under the muscle, you have a capsule, and that capsule is smooth and slides. Smooth surfaces don't heal to each other. So to get the muscle to reattach, you need a raw surface.

There are two ways to create one:

1. Completely remove the capsule from under the muscle and off the chest wall, or
2. Rough up those surfaces so they're raw and will heal together

Then I suture everything down to the chest wall with a big, heavy-duty dissolvable stitch. I don't love permanent stitches in the breast, as I've talked about before, so dissolvable is my preference here.

Sometimes I go in for revision surgery and find genuinely surprising things done to the muscle.

In patients who've had a lot of surgery, the muscle is sometimes released off the sternum and all the way up. What you end up with is a wad of muscle sitting in the upper outer quadrant of the breast. That's a difficult problem and considerably harder to repair than a standard release.

Some surgeons will split the pectoralis in half during a breast augmentation, on the theory that it allows better projection of the implant.

I don't love that idea. And practically, it means that during a revision I don't just have to reattach the muscle at the bottom, I also have to repair a split through the middle of it. It really just depends on what I encounter when I get in there.

For patients with long-term capsular contractures, especially ones that are 10-plus years old, the muscle is often shoved all the way up high on the chest. The contracted implant pushes it upward over years, and it becomes a fibrotic wad that can be really difficult to unroll and pull back down into position.

My philosophy on this is simple:

A muscle left detached and stretched doesn't just look odd, it behaves oddly, and it gets harder to fix the longer it stays that way. Repairing it does add some tenderness to recovery, but the recovery is genuinely manageable, and the result is far better.

• Placing an implant under the pectoralis major requires detaching it from the chest wall, which stretches it into an unnatural position.
• When the implant is removed, that unanchored muscle can make animation look worse than it did with the implant in, because the implant had been holding everything tight.
• Whenever I explant or move an implant from under to over, I repair the muscle back to the chest wall.
• The repair requires creating a raw surface, either fully removing the capsule or roughing it up, then securing the muscle with heavy dissolvable sutures.
• In revision cases I frequently find muscle released too far, split in half, or balled up from a long-standing contracture, each of which is harder to fix.

If you're planning an explant or a plane change and your implants are under the muscle, ask your surgeon directly whether they repair the muscle. It is a question worth asking, and the answer tells you a lot.
